Hi Bert,
- Graphics image
Copy an image between eToys and another activity both way.
- Morph
Copy a morph to another instance of etoy's image through the clipboard or export as a graphics to another activity.
We should handle both of these similarly ... when dragging a morph into some other activity it might be just an image. We should also provide strings for morph (working like the copy text halo menu).
I agree. It's simple for user. Actually, I didn't know there is copy items in the halo menu. That's too tricky UI...
- Formatted text
I think it is harder part than others. Using RTF???
I think it uses the text/richtext MIME standard.
Dragging some text from open office into Squeak produces these formats:
type 0 == 379 text/plain;charset=utf-8 type 1 == 220 UTF8_STRING type 2 == 397 application/x-openoffice-embed-source-xml;windows_formatname="Star Embed Source (XML)" type 3 == 398 application/x-openoffice-objectdescriptor-xml;windows_formatname="Star Object Descriptor (XML)" type 4 == 399 text/richtext type 5 == 400 text/html
(I compiled sqUnixXdnd with DEBUG_XDND enabled)
Thank you for the information. I'll take a look deeper. I thought RTF just because Sugar's clipboard (right edge of the frame) said "RTF File" when I copied in Write activity. Maybe RTF is text/richtext?
We should discuss this with the other platform developers on the vmdev-list.
Sure.
That would be great. As I understand, the proper interaction will be dragging text or objects into the frame. This means the Hand's contents needs to be visually on top of the frame. The only way to implement this properly would be to use the new large cursor support - you can make the cursor be as large as the whole screen.
I didn't quite understand though, You mean that the drag target is drawn on out of the squeak image? That's attractive.
IIUC the Hand already has its own canvas onto which it renders its submorphs, logically these are on a layer above the world. So the basics are there already. I'm not sure if you want to tackle this or if we need a Morphic guru to do it ...
umm, it seems not to be easy to make for me... I prefer to start stupidly simple at first. What about to use X halo for cut, and duplicate halo for copy?
Another issue is the dragging interaction - if there is some selected text, dragging it should move it around. Dropping into the frame should be the equivalent of "copy", but dropping it onto some other place inside squeak should be "cut&paste", that is, delete it from the original place and append to the target.
Yes. Let's follow Write's convention as well as possible.
